Tight Time-Space Lower Bounds for Collision Finding and Element Distinctness under Label Symmetry

Frédéric Magniez, Sebastian Zur

How much memory is needed to retain the quantum speedup for collision finding? For a uniformly random function , the BHT algorithm finds a collision using $O(N^{1/3})…

Even-Cycle Detection in the Randomized and Quantum CONGEST Model

Pierre Fraigniaud, Mael Luce, Frederic Magniez +1

We show that, for every , -freeness can be decided in rounds in the \CONGEST{} model by a randomized Monte-Carlo distributed algorithm with one-side…

Quantum Distributed Complexity of Set Disjointness on a Line

Frederic Magniez, Ashwin Nayak

Set Disjointness on a Line is a variant of the Set Disjointness problem in a distributed computing scenario with processors arranged on a path of length . It was introduce…

Quantum Time-Space Tradeoff for Finding Multiple Collision Pairs

Yassine Hamoudi, Frédéric Magniez

We study the problem of finding collision pairs in a random function by using a quantum computer. We prove that the number of queries to the function…

Quantum Chebyshev's Inequality and Applications

Yassine Hamoudi, Frédéric Magniez

In this paper we provide new quantum algorithms with polynomial speed-up for a range of problems for which no such results were known, or we improve previous algorithms. First, we…
